Soooo I had a bunch of dry rotted coolant lines leak on me and I had to pull the intake and supercharger off the car to replace them. Did that cars back together now it won't start. Every few tries it sounds like it wants too. Checked the spark on both coil packs one is very weak the other has none. It was doing this right before I was trying to get the car on a trailer before removing the intake trying to start the same and eventually did. Sooo any suggestions? I thought maybe the crank sensor but I don't know.

Also I forgot to mention when I got the car the guy replaced one of the coil packs because it started missing on cyl 4 but still was and I never could figure it out and it would occasionally miss on cyl 2 also.

First thing would be to make sure you are getting power and ground trigger signal to the coil pack in question. Have you ran codes to see if there are any primary ignition faults?
